For performing a mining projectвЂ™s break also evaluation, you need to learn about the expenses that are operationalOPEX). As soon as the OPEX is famous, you can easily calculate the mineralвЂ™s cut down level, that will be the break also class, below which it isn’t financially viable to mine the ore. To discover the way I show up with all the cost cost per tonne (OPEX) if your feasibility research is not offered, you are referred by me towards the note at the end of the web web web page.
I first need to show a basic equation which converts a troy ounce into grams per ton before I can calculate the cut off grade:
1 troy ounce = 31.1034768 grms per great deal = 34.2857143 grams per tonne
As you can plainly see, the essential difference between a great deal and a tonne is roughly 10%.
Then, you should be alert to the after conversion rates:
1 ton = 2,000 weight 1 tonne = 2,204.62262 weight = 1,000 kilograms 1 kg = 2.20462262 weight 1% of the tonne = 22.0462262 weight = 22 pounds (curved)
I really believe this conversion that is last truly convenient, since when We read a mining companyвЂ™s news release by which they declare an exercise results of 2% copper, We today rapidly understand this equals to 44 pounds (pounds), or вЂ“ presuming a copper cost of $ 3 per pound вЂ“ a mineral worth of $ 132 per tonne.
